(Summary description)For all stainless steel and stainless steel, pickling and passivation is carried out to remove all kinds of oil stains, rust, oxide scale, welding spots and other dirt. After treatment, the surface becomes uniform silver white, which greatly improves the corrosion resistance of stainless steel and is suitable for various types of stainless steel parts , Plates and equipment. Features: Simple operation, easy to use, economical and practical. At the same time, high-efficiency corrosion inhibitors and fog inhibitors are added to prevent metal over-corrosion and hydrogen embrittlement, and to suppress the generation of acid mist. Especially suitable for small and complex workpieces, not suitable for the application of paste, better than similar products on the market. Usage: Depending on the stainless steel material and the scale of the scale, it can be diluted with water or diluted with water at a ratio of 1: 1 ~ 4; ferrite, martensite and austenitic stainless steel with low nickel content (such as 420, 430, 200, 201, 202, 300, 301, etc.) after dilution, austenitic stainless steel with high nickel content (such as 304, 321, 316, 316L, etc.) is soaked in the original solution; generally at room temperature or heated to 50 ~ 60 degrees After use, soak for 3-20 minutes or more (the specific time and temperature are determined by the user according to their own trial situation), until the surface dirt is completely removed, and it becomes uniformly silver-white and forms a uniform and dense passivation film. , Rinse with clean water.
